Problems Authenticating to an Access Point

If your client adapter is a 40-bit card and LEAP or EAP is enabled, the adapter can associate to but not
authenticate to access points using 128-bit encryption. To authenticate to an access point using 128-bit
encryption, you have two options:

Problems Connecting to the Network

After you have installed the appropriate driver and client utilities, contact your IS department if you have
a problem connecting to the network. Proxy server, network protocols, and further authentication
information might be needed to connect to the network.
Losing Association Upon Resuming from Suspend Mode
(Windows NT and Mini PCI Card Only)
Because Windows NT does not support resuming of mini PCI cards, your client adapter loses its
association to an access point upon resuming from suspend mode. If this occurs, restart your client
adapter to reassociate.

If possible, move your workstation a few feet closer to an access point and try again.
Make sure that the client adapter is securely inserted in your computer's client adapter slot.
If you are using a PCI client adapter, make sure that the antenna is securely attached.
Make sure that the access point is turned on and operating.
Check that all parameters are set properly for both the client adapter and the access point. These
include the SSID, EAP authentication, WEP activation, network type, channel, etc.
Follow the instructions in the previous section to resolve any resource conflicts. If you are using
Windows NT, you may also want to try disabling the Ethernet port.
If the client adapter still fails to establish contact, refer to the
section in the Preface for technical support information.
Purchase a 128-bit client adapter. This is the most secure option.
Disable static WEP for the client adapter and configure the adapter and the access point to associate
to mixed cells. This option presents a security risk because your data is not encrypted as it is sent
over the RF network.
